10.4. Inspecting wiring connections
STEP #1: Refer to instructions for disassembly of the FRONT housing in section 9.1
STEP #2: Remove two (2) screws to take apart main PCB cover. Check wire connections inside
this access panel.
10.5. Cleaning the surface of the evaporator
With the filter removed, inspect the evaporator coils for build-‐up debris (dust, lint, etc.). If
debris is visible, cleaning is needed as follows:
STEP #1: With the Filter removed, remove four (4) screws from the filter cover and set cover
aside. Now the evaporator coil will be accessible.
STEP #2: Using a soft brush and a vacuum cleaner, gently clean away the accumulated
debris from the evaporator coil.
STEP #3: Re-‐install the Filter Cover and the Filter.
WARNING: DO NOT STEAM CLEAN REFRIGERATION COILS OR USE HARSH CHEMICALS.
10.6. Check for indication of low refrigerant charge
STEP #1: Disassemble the front housing (refer to section 9.1).
STEP #2: Run the unit for 15 minutes and briefly remove the cover.
STEP #3: Inspect the evaporator coil.
Look for frost evenly coating the evaporator surface—this indicates a normal charge. At
temperatures above 68°F, the coil may be covered with droplets of water rather than frost.
If partial frosting of condenser and frosting of the thin capillary tubes, is present, this
indicates low refrigerant charge. Contact Ideal Air Support for help adding refrigerant gas to
the unit.
IN THE EVENT OF LOW REFRIGERANT CHARGE STOP USING THE UNIT TO PREVENT
PERMANENT DAMAGE.
